Here, we studied the time-based event expectancies in children with Autism spectrum disorder. Nine children with Autism spectrum disorders and ten (6-11 years) typically developing children participated. In a choice-response task with two different pre-target intervals, participants had to indicate the left or right direction of a target stimulus. The target was predicted by the duration of the pre-target interval with 80% validity. We found that, in children with Autism spectrum disorder, in contrast to typically developing children, the formation of time-based event expectancies was restricted to the relatively longer pre-target interval. This pattern is rather typical for healthy young adults. These findings indicate that children with Autism spectrum disorder are able to form time-based event expectancies, and that, similar to healthy young adults, longer pre-target intervals enable them to make more optimal temporal predictions.
在此，我们研究了自闭症谱系障碍儿童基于时间的事件预期。九名自闭症谱系障碍儿童和十名（6 - 11岁）发育正常的儿童参与了研究。在一个具有两种不同目标前间隔的选择反应任务中，参与者必须指出目标刺激的左右方向。目标由目标前间隔的持续时间以80%的效度进行预测。我们发现，与发育正常的儿童相比，自闭症谱系障碍儿童基于时间的事件预期的形成仅限于相对较长的目标前间隔。这种模式在健康的年轻成年人中相当典型。这些发现表明，自闭症谱系障碍儿童能够形成基于时间的事件预期，并且与健康的年轻成年人一样，较长的目标前间隔使他们能够做出更优的时间预测。
